ProsperoWeb (PRWB00001) 0.2.1 imports the three from libkernel. Only libkernel_sys exported them, and a Linux run of the title does not load libkernel_sys.prx, so the loader stopped with "undefined symbol: LxIacrWiJ3w" before the title started. Cpuset.cpp moves to libkernel whole, because cpuset and cpuset_setid share its set table with cpuset_getid; its test and debt entry follow. rfork_thread and sceKernelRdup move with the prototypes the title uses and still throw.
